"10 yr old Generac GP6500E wouldn’t start. Called around and many want to upsell to permanent. Found Franks and what a delight. Honest, down to earth, affordable for senior. Showed up on time. Changed oil, spark plug. Pulled carburetor and found it dirty and fouled. Got used one from his shop(same day) and installed. Gen started right up on one or two pulls. Battery was dead but showed us how to replace. Highly recommend Frank’s Generator."

"Tony came to the house to diagnose the problem. Then he went out to find the right type of switch that we needed, and came back to install it. He was the only electrician to diagnose it correctly."

Generator Install questions, answered by experts

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.

While the rating will tell you how many watts the refrigerator needs at the peak of its cycle, it requires additional wattage to start. At the bare minimum, you’ll need a 1,500-watt generator to get the fridge up and running after a blackout. A 2,000-watt generator should be sufficient for most home refrigerators.

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.

A home that is 2,500 square feet will likely need a 20kW to 25kW generator. Consult your local generator installer to confirm the generator size needed to power your home before purchasing a new one. Be sure to consider how much power your necessary devices need to run.

Most homeowners won't be able to claim a home generator as a tax write-off. However, a whole-house generator may be tax-deductible in certain situations depending on its purpose. For instance, if it's needed to power essential medical equipment, it may qualify as a medical expense deduction. Also, in some cases, businesses can deduct a generator as a business expense if it supports operations. Always consult a tax professional to determine eligibility based on your specific circumstances and the applicable IRS regulations.
